THOMAS HEATON, OF CORN WALL, NEl/V YORK.

AUTOMATIC FAN.

SPECIFICATION formingpart of Letters Patent No. 258,753, dated May 30,1882.

Application filed Febr ry 8, 1882. (No model.)

To all whom it may concern Be it known that I, THOMAS HEATON, ofCornwall, county of Orange, and State of New York, have invented new anduseful Improvements in Automatic Fans; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification, in which- Figures 1,2,3 represent different methods ofactuating the fan, Fig. 1 being a system of cog-wheels in elevation,operated by a coiled spring; Fig. 2, also a system of cog-wheels drivenby a weight; and Fig. 3, a system of pulleys and belts also driven by aweight, but which is omitted in the drawings for convenience. I

A B O D represent a system of cog-wheels through which the requirednumber of vibrations or movements back and forth of the fan may beobtained, and by which the apparatus may continue in operation for aspecified time.

It will be seen that the number ofcog-wheels may be multiplied so as tomove the fan for a period of twenty four hours, if required. To rotatethis system of cog-wheels by which the fan is set in motion back andforth, a drum, E,

is placed on the shaft F of the cog-wheel A,

around which is coiled a spring, G, one end of which is secured to theframe at H and the other end attached to the wrist-pin I on the face ofthe drum E-the same arrangement as in clock-movements. This springconnterbalances the resistance of the fan, and is of sufficient power torotate the system of cog-wheels steadily and continuously for a statedperiod of time. On the face of the last cog-wheel, D, of this system isplaced a wrist-pin,J, to which is coupled a rod, K, the opposite end ofwhich being secured to the vibrating arm L of the fan, through which pinand connecting-rod, as the pinion D revolves, a vibrating orbaek-and-forth movement is imparted to the fan. The vibrating arm L ispivoted at M, and for convenience may be made of tubing in order toreceive and hold the sliding rod 0, to which the blade 1? of the fan issecured, so that the rod 0 with its blade 1? may be adjustable up anddown, and secured in any required position by means of the thumbnut B.By rendering the blades of the fan adjustable up and down, asrepresented,

the length of the stroke of the fan is regulated to increase or diminishthe agitation of the air, as may be found necessary and desirable.

To govern the back-and-forth movement of the fan when adjusted at anydesired height by means of the sliding rod 0 and thumb-nut R, and thusincrease or diminish the agitation of the air as may be required, is torender adjustable perpendicularly by means of a slot, S, or otherwise,the end T of the flexible connecting cord or rod K, so that by movingthe end of this cord or rod up and down the length of the stroke of thefan is regulated, and the agitation of the air thus governed.

Having described the construction and operation of my automaticfan indetail, as driven by a system of cog-wheels and spring, it is proper tostate that instead of the coiled spring a weight and cord may besubstituted therefor, as represented in Fig. 2 in the annexed drawings,in which case a drum, U, is placed upon the shaft 1 of the cog-wheelA,and so arranged that it may revolve freely when the cord is being woundthereon in raising the weight, as represented in the annexed drawings,Fig. 2, and when the weight is raised thereby may be secured to the faceof the cog-wheel A, and thus by the weight V set the whole system ofwheels in motion, and thereby operate the fan.

-A simple pin, 0, to pass through the drum and into the face of thewheel A, may be employed to attach the drum and cog-wheel, and withdrawnwhen the cord is being wound thereon. By the employmentof this flexibleconnecting-cord d the fan may be operated at any distance from thedriving mechanism, and will obviate any noise and objectionable movementnecessarily accompanying a rigid connectingrod. By connecting one end ofthis cord to the wrist-pin J on the pinion D and securing its oppositeend to the adjustable pin S in the slotted bar L, the fan will be drawnin one direction, and to effect the return movement thereof a coiledspring,f, may be provided and connected to the upper projecting end ofthe bar at 9, so that at every revolution of the wheel D, carrying thewrist-pin, the fan may make two full movements, one back and the otherforward, being drawn in one direction by the cord d, and returned by theaction of the spring, as represented in Fig. 2.

If preferred, a system of pulleys and belts may be substituted in placeof the cog-Wheels, and driven as represented in Fig. 3, employing eithera Weight or spring to operate them.

5 Having thus fully described my improvements in automatic fans, what Iclaim therein as new, and desire to secure by Letters Patent, 18-

In an automatic fan, the combination of the 10 driving mechanism,adjustable blades so coustructed that they may be raised and lowered,and the adjustable flexible connecting-cord d and return-spri ngf, tooperate the fan back and forth, constructed and arranged substantiallyin the manner herein set forth.
